Telescopic Linear Guides

What linear guides should I use?  The navigation choices below are to help you select the right product.

Roller Base Type Linear Guides (aka TELERACE) - Excellent in Dirty or Harsh Environments!

These products use cam roller type wheels as the main rolling element between the guide rails.  These are more suitable for applications where contaminates (i.e., dirt, debris) may become lodged in the rails or raceways.  The cam roller and rail are designed to shed contaminates.  Wipers or End seals provide a dual function by wiping the rails free of contaminates while maintaining a thin lube film between the contacting surfaces.  Click any of the links below to see a particular product list and more details about the product.

Ball Base Type Linear Guide (aka BALLRACE) - Excels in Supporting High Loads!

These products use high grade steel ball rolling elements as the main rolling element between the guide rails.  The advantage with this is a slightly higher load capacity over cam roller type elements.  However, this disadvantage is this design that it is not as dirt or debris friendly. No wipers or end seals are available. So it's best for relatively clean environments.  Click any of the links below to see a particular product list and more details about the product.

SR28 Assembly

What are the materials?  Both the roller and ball base type products are made of cold drawn steel rails.  Each rail goes through a special nitride hardening process.  This process along with e-coating black finish adds a high level of corrosion resistance to the product.  We understand that some applications may require all stainless steel construction. This can be made available upon special request.
